Pollen Count & Forecast for Cambridge, Cambridge

Cambridge’s spring allergy season (March-May) is dominated by Birch pollen from ubiquitous street trees and College Gardens; Oak pollen follows, originating from established urban parks like Parker’s Piece and Jesus Green. Summer (June-August) peaks with pervasive Grass pollen from the River Cam’s meadows, Stourbridge Common, and surrounding Fenland fringes.

The city’s flat topography and dense green spaces can trap airborne pollen, locally intensifying concentrations; late autumn/winter (September-February) introduces Mould spores, exacerbated by damp conditions along the Cam’s banks and decomposing leaf litter within areas such as Cambridge University Botanic Garden.
